octopus pump air and noisy?

We have an older octopus reversing pump on our recently bought second hand sailboat.
The direct replacement would be this one: https://www.boemarine.com/octopus-re...-cylinder.html

We changed the oil just now and we are wondering what the noise output from the pump/cylinder should be, or at least what is acceptable?
I've added a small video link (https://drive.google.com/file/d/1Zad...ew?usp=sharing) and it seems the pump is very loud, no?

Also we purged the air following the instructions (https://productimageserver.com/liter...de/44319QG.pdf) and no more bubbles come out when doing so but when all is closed back
up and connected and we use the steering wheel we hear some noise in the cylinder which I think still indicates air being present in the cylinder? (second video where in the middle you can here the sound: https://drive.google.com/file/d/1uOH...p=drive_link)?
If it is air how can we get it out as following the manual doesn't get it out. Also the oil is topped up. Putting any more into it will overfill it I think.

We are thinking about getting a new one and keeping this one as a spare. Do the new octopus pump generate noticeable less noise?

Hi GordMay, we indeed came across that file already.
Our main question might be if there is still air in the system , which seems like it, and is this causing the excessive noise?
And how to get that air out!
